Screen Time and Seizures: What You Need to Know
In today's digital age, screens have become an inseparable part of our lives. In India, where over one billion people are now internet subscribers, the impact of digital habits is profound. While many individuals experience sore eyes or neck stiffness from prolonged screen exposure, neurologists are drawing attention to a more serious concern: the link between excessive screen time and seizures.
A seizure occurs when there is a sudden burst of abnormal electrical activity in the brain, leading to changes in awareness, movement, or behavior. Dr. Sweta Singla, a neurologist at Manipal Hospital in New Delhi, highlights that individuals already vulnerable, such as those with epilepsy or undiagnosed neurological conditions, are particularly sensitive to triggers associated with modern screen usage.
Late-night scrolling and binge-watching have become common, especially among young adults, often at the expense of sleep. Sleep deprivation is a significant trigger for seizures, as it disrupts brain rhythms and prevents the necessary reset that deep sleep provides. The National Institutes of Health (NIH) warns that sleeping less than seven hours a night can increase the risk of various health issues, including neurological vulnerability.
Not all seizures are related to sleep loss; some are triggered by what is displayed on screens. Photosensitive seizures, which can be triggered by flickering lights, are more prevalent among teenagers and young adults. The World Health Organization (WHO) cautions that these preventable triggers can heighten brain sensitivity, leading to a lower threshold for seizures.
With average daily screen time now exceeding six to seven hours, the risk of seizures is widespread. Uncontrolled triggers can lead to refractory epilepsy, which may require complex medical or surgical interventions. However, doctors emphasize that early lifestyle changes can make a significant difference.
Simple changes, such as establishing a balanced life, ensuring adequate sleep, and practicing mindful screen use, can protect brain health. Dr. Singla advises that these changes are not optional but necessary to prevent serious problems associated with seizure triggers.
The brain remains active even as we scroll through social media or check emails. It is essential to recognize that our digital habits can significantly impact neurological health. The focus should not be on quitting screens entirely but rather on utilizing them in a way that does not push the brain into a state of survival. Your brain is working harder than you realize, and it’s crucial to adopt healthier habits for its well-being.
